Application filed June 10, 1914. Serial No. 844,283.

To all whom it may concern:

Be it known that I, NANCY E. GRAVES, a citizen of the United States,residing at Knowles, in the county of Madera and State of California,have invented certain new and useful Improvements in Knee-Rests forCrutches, of which the following is a specification, reference being hadto the accom panying drawings.

This invention relates to attachments for crutches, and particularly toa knee rest which is adapted for connection to the stem of a crutch:

An object of this invention is the provision of a knee rest forcrutches, which includes an angular base plate, one end of the baseplate being secured to the stem of the crutch, the other end of the baseplate extending inwardly at an angle to the crutch to support the knee,the base plate having a cushion suitably connected thereto to provide asoft rest for the knee.

With this and other objects in view, my invention consists in the novelconstruction, combination, and arrangement of parts to be hereinaftermore fully described, claimed, and illustrated in the accompanyingdrawing, in which,

Figure 1 is a side elevational view of my improved knee rest, showingthe same attached to a crutch; Fig. 2 is an edge elevational viewthereof; Fig. 3 is a perspective view of the base plate and a portion ofthe crutch, showing the registering openings therein; Fig. 4 is aperspective view of the cushion; and Fig. 5 is a perspective view of thecover. 1

Referring more particularly to the drawing, the numeral 1 designates acrutch, the stem 2 of which is provided with a pair of vertically spacedopenings 3, and 4 designates the elongated base plate of my improvedknee rest, the base plate being bent intermediate of its ends, so thatthe ends thereof are disposed at substantially right angles to eachother. One end of the base plate is disposed vertically and is providedwith a pair of openings 5 which register with the openings 3 in the stemof the crutch,

and bolts 6 are disposed through the registerlng openings 3 and 5, nuts7 being threadably mounted upon the free ends of the bolts to fasten theplate to the crutch. The inwardly extending end of the plate 4 is curvedas at 8, to conform to the curvature of the knee, and mounted upon theplate is a cushion 9 which is bent so that the same entirely covers theinner face of the base plate. The covering 10 of leather or othersultable material is arranged to entirely cover the cushion 9 and thebase plate 4, the cover ng being provided with a slit 11 in one side,whereby the same may be quickly engaged over the base plate and cushion,the edges of the slit being stitched together after the covering hasbeen applied to the device, so that accidental disengagement of thecovering is prevented.

In assembling my improved rest, the bolts 6 are first disposed throughthe openings 5 in the base plate, whereupon the cushion 9 is placedagainst the inner face of the plate, the cushion covering the heads ofthe bolts and the covering is then disposed to entirely inclose the baseplate and the cushion, and when the edges of the slit 11 are stitchedtogether, the bolts 6 are disposed through the openings 3 in the stem 2of the crutch, so that the same are in position to receive the nuts 7,which, when turned upon the bolts to engage the opposite face of thestem, securely fasten the knee rest to the crutch.

It will be seen that my improved knee rest is of such construction thatthe same may be quickly and easily applied to or removed from a crutch,the rest serving to support the weight of an injured leg of a personwhich must ordinarily be held by the person in a bent position so thatthe foot of the injured leg is spaced above the ground. By the provisionof the rest, the strain of holding the leg in this unnatural position isobviated, and the cushion supported upon the inner face of the platepresents a soft surface to the knee.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent, is

A knee rest for crutches comprising an In testinnon whereof l hereuntoaflix my angular base plate, one end of the base plate slgnature in t epresence of two witnesses. being disposed vertically for connection tothe stem of the crutch, the other end of the a NANCY GRAVES 5 base plateextending inwardly from the Witnesses: X

crutch to support the knee, and a cushion C. F. Pnncmno,

carried by the base plate. WAL-T'ER A. SMITH.
